Marsh Island dominates the northern portion of this coastal survey, where the land fragments into the waters of the Gulf of Mexico. The geography here is defined by the complex aquatic network of Oyster Bayou, along with its West Branch and East Branch, which carve through the low-lying terrain. This coastal landscape is marked by prominent landforms such as Mound Point and South Point, providing critical reference points for navigation at the edge of East Cote Blanche Bay. Further offshore, the Shell Keys stand as isolated features in the open water. This 2015 data illustrates the delicate balance of the Louisiana shoreline, showing the intricate relationship between marshland and the tidal influences of the Gulf.
